Effects of Electrochemical Potential on Stress Corrosion Cracking of Aluminum Alloy 7079-T6 in Salt Water.

Abstract

Cathodic protection schemes can greatly extend the useful life of the high strength aluminum alloy 7079, but because of general cathodic wastage at high cathodic currents, cathodic protection cannot produce indefinite immunity to stress corrosion cracking. For long-term applications in sea water requiring this alloy a high-integrity paint system backed up with a galvanic anode system would be indicated for maximum reliability. (Author)
